This morning Apple released updates for the iPhone bringing forth a bevy of new features including the slick new WiFi music store, better iPod controls, your choice of incoming SMS alerts, and other minor tweaks and refinements throughout the iPhone. The iPhone gained a few features already introduced in the iPod Touch like bringing up media controls when the home button is double tapped and a cool trick where double tapping the space bar inserts a period and a space to help cut down on finger taps.

The WiFi music store lets users purchase songs on-the-go using any WiFi hotspot which essentially puts the entire multi-million track library of iTunes in your pocket – perfect for a quick impulse buy from time to time. It would be perfect for the impulse-heavy consumer like me – if it worked on my iPhone!

I’m having store authorization problems so I can’t actually buy anything right now. It’s rejecting my credentials to the point of locking my account, when I know I’m entering them correctly. I even verified my credentials on a desktop just to make sure I wasn’t having a senior moment.

I wrote up up a more detailed report of my WiFi Music Store experience for Gear Live if you want to know more. For now I’ll have to sulk about with my existing library while on-the-go and be content with the other features released today.
